Long response: For soup, I most often use a few vegetables as a foundation, seasoning it ethnically or regionally or according to the meat I do or don't decide to add. (I used to think the meat should be predominant, with vegetables as filler, but I've changed that around.) If I use tomatoes, whether fresh or store-bought canned, I drain them very well before adding, to keep a more clear broth and less of a strong tomato taste---which it took me 45 years of cooking to figure out. Chili Verde (Colorado's popular Green Chili) is really just a Mexican pork stew or soup, and I make that very often, for smothering filled burritos or eating with tortillas. In a couple of weeks I'll make a pot of Brunswick Stew for freezing in small batches, using my mother's recipe, which she made for church suppers in Georgia, for decades (only corn and tomatoes, no other vegetables). I also make chicken stew, with varying spices and herbs. I especially like chicken or pork, cooked tender with cilantro and lime, before adding it to vegetables in a broth for final simmering.
From the time I was a young teenage cook, I have simmered traditional stew ingredients together and served with rolls or biscuits. Everyone loved it, but I felt it could be better. Now, as a result of cooking with my daughter and re-reading recipes by professionals I admire, I try to cook in a way that lets individual items show and be tasted, as well as being part of the whole dish. It's still a stew or soup that everyone loves, but I like it better. I'm still working on developing an appreciation for a wider range of ingredients!
